java - 如何为相互SSL覆盖Spring Boot keystore /信任库

我有一个Spring Boot应用程序。它的application.yml是从在线资源中获取的。它包含以下用于相互SSL的配置：

server:
  ssl:
    enabled: true
    client-auth: need
    key-store-type: PKCS12
    key-store: http://{config server url}/keystore.p12
    key-store-password: {keystore password}
    trust-store-type: JKS
    trust-store: http://{config server url}/truststore.jks
    trust-store-password: {truststore password}
  port: 8443

运行应用程序时，出现以下错误：

java.io.IOException: DerInputStream.getLength(): lengthTag=111, too big.
    at sun.security.util.DerInputStream.getLength(DerInputStream.java:599)
    at sun.security.util.DerValue.init(DerValue.java:391)

    at org.apache.tomcat.util.net.AbstractJsseEndpoint.createSSLContext(AbstractJsseEndpoint.java:97)
    ... 23 common frames omitted

但是我可以通过编程方式很好地打开密钥库和信任库。 （如下所示）

private KeyStore getKeyStore() {
    KeyStore keyStore = KeyStore.getInstance("PKCS12");
    try (InputStream is = readCertificateFromURL(new URI(keyStoreURL))) {
        keyStore.load(is, keyStorePassword.toCharArray());
    }
    return keyStore();
}

private InputStream readCertificateFromURL(URI uri) throws IOException {
    RequestEntity<Void> requestEntity = RequestEntity.get(uri)
         .accept(org.springframework.http.MediaType.APPLICATION_OCTET_STREAM)
         .build();
    Resource resource = new RestTemplate().exchange(requestEntity,Resource.class).getBody();
    return resource.getInputStream();
}

如何告诉Spring Boot选择这些密钥/信任库，而不是application.yml中定义的密钥/信任库？

我在网上发现的唯一内容是关于覆盖密钥库/信任库路径，而不是覆盖密钥库对象本身。

最佳答案

Spring属性中javax.net.ssl.trustStore和javax.net.ssl.keyStore的值及其对应的值必须是文件系统路径。如果将它们复制到本地文件系统并引用这些文件，您的方法是否可行？
